Version 2.2.7 build 7/8 issue

The actual result is that there is a table for the superclass.  When I try to examine it in ObjectDB Explorer, it throws a NPE. #1 2011-07-30 07:51 The problem could be my expectation, since I'm fairly inexperienced with JPA.  But here is the problem: ...

This may be related to the fix for the problem described in this thread: Wrong data stored in date only fields. The object and its date and time fields are the same as in the referenced thread.
